Let A be a simple unital AT algebra of real rank zero such that it has a unique tracial state { and K 1 (A) is neither 0 nor Z. For each . # Hom(K 1 (A), R) with dense range in R we construct a closed derivation $ in A which generates a oneparameter automorphism group : of A such that {($(u) u\*)=2?
